Why does a ship made of iron floats while a piece of iron sinks?

Because the ship contains a large amount of air in it. But iron nail doesn't have any space to contain air in it. Air is a lightest thing. That can't sink in water. This method is used in submarines to sink it. There is a tank in the submarine. When they need to sink it they fill the tank with water. To float it they use to fill the tank with air.

∙ 14y agobecause the ship has air in its hull. Its a little bit more complicated putting it simply.
We heard of Archimedes' principle, the weight of fluid displaced is equal to the weight of the object. A iron ship floats because it displaces a large amount of water and the pressure of the surrounding water exerts a large upthrust on it.
The nail sinks because the upthrust is not big enough to equal the weight of the nail, assuming the nails density is greater than water.

∙ 8y agoWhether a body will float or sink depends on the density of the body. Density of a body is the mass divided by the volume of the body.
Density of an iron pin is more than water so it sinks. The density of a ship is mass of the ship divided by the volume of the ship. Although the ship is made of iron, the volume of the ship is so huge that the density becomes less than the density of water. The reason being, ship is not a mass of solid ron. There is lots of empty spaces and other less dense substances within the volum of the ship.

The density of an iron ball is more than water so it sinks, but the density of ship is less than water so it floats.
Wiki User
∙ 11y agoThe density of an iron nail is greater than that of water whereas the density of iron ship is lesser as compared to water.Also,the streamlined shape makes the iron ship to float.
Wiki User
∙ 12y agoIt is the principle of displacement. A ship is hollow, a nail is solid. The ship will displace more water than a nail would.
Wiki User
∙ 9y agoThe general rule is that an object will sink if it has a greater density than the liquid in which it is placed.

How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
Can a nail float in water?
The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.
What are the current trends in modern bath sinks?
One of the trendiest varieties of bathroom sinks are vessel sinks--these sinks have a free-standing bowl that is mounted to a countertop, reminiscent of old wash basins. These are available in glass, porcelain, cast iron, and even marble. For fixtures, brushed nickel is the trendiest finish.
What happens to iron placed in a test tube with a stopper?
Iron and oxygen in a test tube alone will not react (observed by placing a piece of iron in a test tube with a stopper).Iron and water in a test tube alone will not react (observed by completely submerging a piece of iron in water in a test tube with a stopper).Iron, water and oxygen in a test tube will react (observed by placing a piece of iron in a test tube and submerging half of it with water). The following reaction will take place: iron + water + oxygen ----> hydrated iron(III) oxide. Hydrated iron(III) oxide is the chemical name for rust, which will appear as orange flaking on the piece of iron. To speed up this reaction you can use a bit of salt as a catalyst.
What is function of iron stand?
The iron stand is used as a piece of laboratory equipment. It is meant to support an iron ring in order to hold items like beakers and flasks during heating.
Why iron nail floats on mercury but sinks on water.?
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
Why wood floats on water?
the density of water is higher than the density of wood... & so an iron piece sinks & a ton of wood floats...
What happens to iron and sulphur when you add water?
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
What would a compound sentence be using the word sink in?
Wood floats on water, but iron sinks into it.
Why does an aluminum cube sink but a sheet of aluminum float?
Have you heard of Archimedes. Well he stated that the weight of water displaced by an object is equal to the weight of the object. From here we conclude that object being more denser than water sinks those being less dense than water floats. An Aluminum cube has a much higher density than that of water and the sheet is less dense than water. Thus the former floats while the latter sinks. Now you also might have noticed that an iron nail sinks while an iron ship floats. I hope now you can answer this question!!
A cork piece floats on water but an iron nail sinks give reason?
Things that are less dense than the water they displace will float (like cork) Things that are more dense than the water (like a nail) sink.
Why should float on water while it is made up of iron sinks in water?
Anything which floats on water can only do so if it displaces, or moves out of the way, its own mass of water. Wood floats because it displaces a small amount of water, a large lump of iron is very heavy so it will keep displacing water until it has displaced its own mass.
Does water have greater density than oil?
No, water has more density than oil. If something denser than water(Eg=Iron) is dropped to water, it sinks, while less denser will float. Oil floats on water. Really I've tested it
Is an objects density determines whether it floats or sinks in water?
yes it does. try to sink a cork. it doesn't sink but on the other hand a iron nail does.the higher the mass the more the density and so the object sinks.
Why does iron sinks while iron boat floats on sea?
jk its because the boats are full of air, which is less dense than water, and so is unable to sink. if there is a hole in the boat, the air will proceed to be replaced with water, and therefore sink. There must be enough air in the boat to be able to carry the large weight of the iron.
How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
Can you use the word out of wood in a sentence?
Would you chop this wood for me? is an example
